Application iiled April r.930, 1914. Serial No. 833,047.

To all whom 'it may concern Be it known that I, RAYMOND W. DU'LL, a citizen of the United States of America, and resident of Chicago, Cook county, illinois, have invented a certain new and useful Improvement in Separators, of `which thefollowing is a specification.

My invention relates to separators of the 1 kind employed in separating water from sand, and more 4particularly'to sand separators oi' this character in which areceptacle receives the sand and water, `and in which means are provided for discharging the water from the top of the receptacle and the sand from the lower endthereoh the automatic discharge of sand being'controlled by a valve whi'chsis operated by the downward movement of the receptacle under `the weight of the contents thereof.

Generally stated, the object of my inven tion is to provide a novel and highly etlicient sand `separator of the foregoing general character.

A special object is to provide a novel construction and arrangement whereby the receptacle moves bodily downward, instead of tilting about `an axis, yand whereby a sand valve 'at the lower end of the receptacle` is automatically `opened and closed by this bodily `up and `down movement thereof.

It is also an `object vto provide certain d`etails of construction and combinations tending lto increase 'the general efficiency of a sand separator oithis particular character and tending to render thesam'e more satisfactory and yk'certain in its operation rthan heretofore. n f

To the y'foregoing yand other useful' ends my invention consists'in matters hereinafter set forth andclaimed. y

In the accompanying drawings, Figure 1 is a side elevation of sand Aseparator embodying the principles of my invention. Fig. A2 a horizontal section, on 'a smaller scale, on line 2-2 in Fig. l1. Fig. 3 is a vertical section, yon a smaller scale, on line 3--3 in Fig. 1. Fig. et -is a perspective, also on a smaller scale, of kthe battle plate which `is employed fior preventing' lthe sand trom overflowing with water. y f

As lthus illustrated, and referring more particularly to Fig. l, my invention comprises a receptacle which *is lshaped like an inverted cone, being provided with hangers trat the Tripp/ei'y feud thereof, and with a` discharge opening c1 at the lower end therefor.

Said hangers iave knife edges a2 which rest on the upper edges of the plates c3, the latter having seats or notches a4 for this purpose.,` rThese plates a3 are also provided with openings a5 for the U-bolts a6 which extend vertically through 'the beams B or other structural members ot' the .trame upon which the separatoris supported rlhis trarne, it will be seen, affords access to the top of the receptacle. A lever C is secured to the plate a3 at the right in Fig. l, and a leverD is secured to the plate o3 at the lett in the iigure. The two levers are of different lengths, as shown, and the end of the lever D is connected with the middle of the lever C by a link E of any suitable character. lThus a supporting mechanism is provided for sus-` taining the weight of the separator receptacle. Disposed a distance above these levers is a counterbalance arm or lever F which is pivoted at 7 upon a bracket f1 secured to the stationary frame of the separator, or which is joined to the supporting mechanism in any suitable manner. A link f2 is provided for connecting the end of the lever with the short end of the lever F, the. longer end of the latter being provided with a counter-weight f3 which is adjustable thereon for the purpose or regulating the operation oi: the separator. In other words, and by means of this counterbalancing weight, the receptacle can be caused to move downward with either a yiull load or any fraction thereof.

The automatic valve C controls the opening al and is fixed to the lower end of a rod f/ 'that slides up and down in a tube or housing g1 disposed centrally of the receptacle, the upper end of said tube being lrmlyheld in place by a clampy g2, or bv any other suitable means. T he lowerend oi said tube or guide g1 can'be held in place in any suitable manner, it being understood that this tube is preferably large enough to give the said rodsome lateral play therein. The upper end ofk said rod is connected with the lower end of the link E, it being understood that the three pivotal connections of this link are loose or of any other character which will permit the two levers `C and D and the rod g to move up' and down in the desired manner and without causing any binding or cramping of the parts. ifVith this const-rnction and arrangement, the valve G moves downward faster than the receptacle, with the result that the yd'iseh'arge opening al is VGr is provided with meansr to engage the valve seatat the lower end of the receptacle,

hus forming means on said rod to limit the motion thereof and vthereby ydetermine the extent of movement oic the receptacle. 1A nut g3 on the rod may serve as an radjustable stop to limit the downward movement, as the valve will not open farther after the nut g3 engages the top of the clamp g2. Vthus determining the extent to which thefvalve will open when the receptacle movesdownward. However, the downward movement can be limited by any suitable means. After the sand has been discharged in this manner, the receptacle then automaticallv moves upward. Y Y

Y a horizontally disposed baflie plate H is provided near the top of the receptacle, within the same, and at one side of the center thereof, said plate having a vertically disposed flange ft which is secured to the clamp 92st the center of vrthe structure, and which has its outer endssecured to the receptacle by brackets l, or by any other suitable means. 1n this way the upper end of theftube g1 is heldin position by the baille plate. rlhe edge portion 7a2, of this bailie plate is disposed a distance from the sides of the receptacle, thereby forming a space h5, and is secured by brackets h4 to the side walls of the receptacle. rlhe water and sand are discharged on to the plate H toward the flange It thereof, the water overilowing the said ilange'and escaping from the-other side of the'receptaclewhere it is Y discharged therefrom through a'sp'out L, or

by any other suitable means. On the other hand, the sand washes backward away from the flange 7L, with a certain percentage of o the water, and is discharged 'through the space ,7b3 to the receptacle. 'In this way the 'sand is all precipitated into the receptacle,

and practically nothing but water and the mud held in suspension thereby are discharged rom the spout at the other siderof vthe receptacle,

do not limit myself to the exact con-Y struction shown and described..
